Dye movement and low-resistance junctions between reaggregated embryonic cells
TLDR
Reaggregated cells from Xenopus laevis embryos in blastula through larval stages become electrically coupled within 20 min of the beginning of aggregation and some of these cells can exchange fluorescein injected intracellularly.About:

Functional connections between cells as revealed by dye-coupling with a highly fluorescent naphthalimide tracer
TL;DR: Dye-coupling, readily observed because of the low molecular weight and the intense fluorescence of the new dye, may serve as a general method of tracing certain functional connections by morphological means, and of studying the transfer of small molecules between cells.
Book ChapterDOI
Structure and function of intercellular junctions.
TL;DR: This chapter reviews the morphological information on intercellular junctions derived from thin-sectioning, negative staining and freeze-cleave techniques, as well as from x-ray diffraction and biochemical investigations, and correlates the structural parameters with known or proposed physiological functions.
Journal ArticleDOI
Gap junctions between the oocyte and companion follicle cells in the mammalian ovary.
TL;DR: Tracer and freeze-fracture electron microscopy of the ovaries of neonatal rat and adult mouse, rat, rabbit, and primate have revealed the presence of gap junctions between follicle cells and oocytes.
Journal ArticleDOI
The appearance and structure of intercellular connections during the ontogeny of the rabbit ovarian follicle with particular reference to gap junctions
TL;DR: Lanthanum tracer and freeze-fracture electron microscope techniques were used to study junctional complexes between granulosa cells during the differentiation of the rabbit ovarian follicle to identify gap junctions that appear to increase in size with further differentiation ofthe follicle.

Positional information and the spatial pattern of cellular differentiation
TL;DR: These concepts provide a unifying framework within which a wide variety of patterns formed from fields may be discussed, and give new meaning to classical concepts such as induction, dominance and field.

Hexagonal array of subunits in intercellular junctions of the mouse heart and liver.
TL;DR: A new technique, based on the observations of Doggenweiler and Frenks, wMch has allowed us to demonstrate the presence of similar structures in sections of mouse heart and of mouse liver, and it seems likely that, as lanthanum solutions are brought to a high pH, a colloidal compound is formed which permeates the extracellular space as a tracer.

Diffusion in Embryogenesis
TL;DR: A simple order-of-magnitude calculation suggests that diffusion may be the underlying mechanism in establishing morphogenetic gradients in embryonic development.
